PAVEMENT FOFI STABLES.

SPECIFICATION forming part of Letters Patent No. 469,044, dated February16, 1892.

Application filed June 15. 1891.

To coZZ whom it may concern.-

Be it known that I, J OHANN J UNGBLUTH, invalid, of Cologne, in theKingdom of Prussia, German Empire, have invented certain new and usefulImprovements in Pavements for Stables, of which the following is aspecification, reference being had therein to theaccompanying drawings.

The invention relates to outlets or drainchannels for pavements, whichchannels are gradually deepened and enlarged laterally and are adaptedfor the flooring of stables, baths, slaughter-houses, and the like.These outlets or drains are constructed separately of any suitablematerial, such as iron, clay, cement, 850., and are employed in such wayas to receive all the drain-water from the surface to which they areapplied and conduct it away below the surface, so that the latter may bekept comparatively dry. These drain-pipes, as stated, are constructedseparately and are therefore easily transported to any place for use.The pipes are in shape something like an elongated oval incross-section, and at one end of the oval have a narrow opening, so thatthere is a narrow slot running along the entire length of each pipe.They are put into the ground with the slot uppermost, and are thensurrounded by a layer of concrete, or the flooring may be made of stone,or cement, or any other suitable material. I In order to facilitate theflow of the drainage into these pipes, the flooring is slightly inclinedtoward the slotted channels. They are also thus made comfortable foranimals in walking,

standing, or lying thereon. a

In the accompanying drawings, Figure Iis a perspective view of aflooring with the inlaid channels or drain-pipes; Fig..II, acrosssection of the same, taken on the line 0c 00 of Fig. I; Fig. III, asimilar section taken on the line y yof Fig. I, and Fig. IV alongitudinal section in perspective of one of the pipes detached.

' In the drawings, F represents the drainpipes, which, as stated above,are made separately and of any suitable material. These pipes are of asomewhat oval shape in crosssection, as seen in Figs. I and II; but theup per end of the ovalis contracted and is slotted, as also seen in thesame figures. Near its upper edge each side of the pipe has a shortSerial No. 396,276. (No model.)

sharp bend inward about at right angles to the face of the pipe, and isthen bent upward at about right angles and carried up straight to theupper edge. This provides'a projecting edge y, extending inward slightlyon each side of the pipe just below the slotopening and standingcompletely away from theinner faces of the pipe below. It will also beseen that the opening of the slot above these projections is slightlytapering upward, or, in other words, is flaring from the extreme edgesdownward to these projections, as seen in Figs. I and II. Thedrain-pipes are also made much smaller at one end than at the other, theenlargement being gradual between the two ends. The enlargement,however, is effected by deepening and widening the pipe below theprojection y, while the slotted portion remains practically the same, asseen in Figs. III and IV. It is evident that if the pipes are laid withtheir upper slotted edges in a horizontal plane, or thereabout, therewill be a gradual incline at the bottom thereof from the smaller end tothe larger. In some stancessuch, for instance, as the flooring ofstables-a slight inclination is usually given to the flooring itself, inwhich case the down- Ward inclination of the pipes will of course becorrespondingly increased. These drainpipes F are set eitherhorizontally or at any desired inclination in a foundation of fine andwell-strained sand, immediately above which the space between the pipesis filled up part way with a layer of concrete B, and upon the latter isa top layer 0' of any suitable material, such as brick, concrete cement,wood, or any other material suitable for flooring in different places.This upper layer fills the entire space between the drain-pipes up tothe slot-ted edges thereof, and, if desired, the sections between thepipes may be raised slightly in the center, so as to provide a ridge f,running lengthwise between the pipes. This provides a slight inclinationeach way from the ridge toward the respective pipes and facilitates thedrainage into the latter. If the side walls of the pipes were straight,the material passing into them through the slots would in some instancesfollow along the sides, clinging thereto, instead of dropping directlydown to the bottom of the pipes. This of course prevents a complete andsat 5 necessarily drop down from these projections,

and so there will be no adherence of material to the walls of the pipes,which is objectionable because gradually filling up the latter and. alsoinfecting the air by retention Withinthe drains. With my constructionthe material passing into the pipes, whether liquid or semi-liquid, mustnecessarily drop to the bottom of the drains and be carried 01f by theinclination of the latter. Of course a suitable water-supply isprovided, the inlets to each drain-pipe being located at the highestportion thereof, which will be at the smaller ends, and with thisprovision the drain-pipes may be flushed whenever required.

Having thusdcscribed my invention, what I claim as new, and desire tosecure by Letters Patent, is

' 1'. A. drain-pipe for stable flooring and other like purposes,provided with an inletslot running lengthwise of its upper surface andhaving sharp angular internal projections y arranged a little below theslot, substantially as described.

2. In a composition flooring for stables and other like purposes, thedrain-pipes F, slotted lengthwise along the surface and provided withangular internal projections y a little below the slot, in combinationwith a lower layer of concrete B, arranged between the said pipes, andan upper or surface-layer C of cement or other suitable fioor surfacematerial, substantially as described.

Inwitness whereof I have hereunto set my hand in presence of twowitnesses.
